Removing a stubborn harmonic balancer or pulley is made easy with the Powerbuilt Harmonic Balancer Puller / Pulley Installer Kit. This is the go-to kit when swapping out old harmonic balancers with threaded holes or removing and replacing crankshaft pulleys. The kit includes a special puller for balancers with threaded holes found on many US-made V6 and V8 engines. It even covers your 1990 and newer Chrysler engines. Simply line up the supplied 2/3 combination yoke to the balancer, attach to the vehicle with the correct supplied bolts, and turn the screw until it breaks free. Easy enough for the weekend mechanic, durable enough for the pros. Full detailed instructions and usage photos included in the durable organizing case.
